Hi all,

I get an error from UnityLinker (see below) in Unity 2019.2.2f1, Android and PC Standalone build. The project also uses LWRP which, I assume, is not so important here. I did not test with standard rendering. I can reproduce this error in an empty project just importing the OPCUA4Unity asset. Other settings are IL2CPP, Net Standard 2.0.

Edit: Maybe it is helpfull to know, that Mono Scripting Backend does not run into this.

Full error message:

Hi,

I am using OPCUA4Unity in my Hololens Unity project. An exception is thrown when I try to connect to an OPCUA server from the Hololens. Here is the output:

"The type initializer for 'Opc.UaFx.Client.OpcClient' threw an exception. at game4automation.OPCUAConnection.Connect () [0x00000] in <00000000000000000000000000000000>:0
at game4automation.OPCUA_Interface.Connect () [0x00000] in <00000000000000000000000000000000>:0"

I am able to connect just fine in Unity Editor, but not when connecting in Hololens.

I have ensured that the build settings are correct (IL2CPP, .NET 2.0 compatibility), and have set the permissions to allow internet access in Hololens. I am on Unity 2018.4.8f1, and have tried upgrading my project to 2019.1.14f1 but that did not fix the issue.

Let me know if you need more information!

Dear game4utomation team,

Recently we bought the Game4Automation Pro Asset in Unity, and so far we really like it.

We set up a simple project in Simit and managed to get the interface working with the shared memory solution.

For this we used the Update() method off Unity, now we would like to use a event based system to reduce the load on the system. In the PLCOutput class the event SignalChanged is available and we tried to implement this.

So in this example we would like to toggle a bool to change the color on a traffic light.

public class Verkeerslicht3 : NetworkBehaviour

{

public Material yellowMaterial;

public PLCOutputBool yellowEnable;

public MeshRenderer yellowMeshRenderer;

void Start()

{

yellowEnable.SignalChanged += OnYellowEnableStateChange;

}

private void OnYellowEnableStateChange(Signal obj)

{

RpcSetGeel(obj);

}

[ClientRpc]

private void RpcSetGeel(bool state)

{

yellowMeshRenderer.material = state ? yellowMaterial : disabledMaterial;

}

But if we toggle the Bool in Simit the OnYellowEnableStateChange is not called.

Can you help with this?

We are having issues with models generated from Solid Edge. Assembly positions and part colours don't always seem to be respected.

I note that the documentation mentions similar issues with NX and that a fix is due soon. Will something similar for Solid Edge available?

Hello,

I would like to create a digital twin of an already existing system, which is using a S7-1500 controller.

Is the basic version capable to create a bidirectional communication between the digital twin and the real system?

Does a change in state of the physical object directly lead to a change in state of the digital twin and the other way around?

Cheers,

Leon

Dear game4automation team,

so far the OPCUA4Unity asset works very smooth. Great work!

In my project I tried to update my data like you show in the DemoTextWithDelegate example. But the subscription object returned in OPCUA_Interface :

sub = connection.SubscribeNodeDataChange(nodeid,del);

is pretty much empty:

I used UAExpert to test the subscription with the same node id, which worked. As far as I can tell I do not get any warnings or errors. Here is my code how I subscribe:

private OPCUANodeSubscription _safetyLevelSubscription; //subscription is a class member
[...]
_safetyLevelSubscription = _interface.Subscribe(node.NodeId, SafetyLevelNodeChanged); //this is the call
[...]
 public void SafetyLevelNodeChanged(OPCUANodeSubscription sub, object obj) //this is the delegate signature

Now, I noticed that the OPCUAInterface gameobject holds pretty much all the nodes of the top node as childs and keeps them up to date. At least in the editor. Wouldn't it be best practice then to always access those child OPCUA_Nodes instead of adding an additional subscription?

Thanks for your thoughts!

JG

EDIT:

Maybe I should add, that the delegate is not called when the value on the OPC UA server changes. I assume it is due to the null ptr in the subscription. Also, I use a codesys opc ua stack.

Hi all!

I am using the OPCUA4Unity asset in my project. When I run it on android devices an exception is thrown in game4automation.OPCUAConnection.Connect(). Here is the full output:

The type initializer for 'Opc.UaFx.Client.OpcClient' threw an exception. at game4automation.OPCUAConnection.Connect () [0x00000] in <00000000000000000000000000000000>:0
at game4automation.OPCUA_Interface.Connect () [0x00000] in <00000000000000000000000000000000>:0

UnityEngine.Logger:Log(LogType, Object)
game4automation.OPCUA_Interface:Connect()

I am able to run it in Unity Editor aswell as Win Standalone App. I am also able to connect with another OPC UA client from the same android device to the server.Is Android not supported?

Please let me know if you need additional infos!

JG

안녕! OPCUA 시험 버전이 있습니까?

나는 경험하고 구매하기로 결정하고 싶다.

is it possible to call method of OPCUA server?
